I'm heading to Turkey in a few weeks for a trip that will last about 6 weeks. I have a Verizon iPhone 4, so I can't do the typically-suggested "replace the SIM card" thing since there are no SIM cards (right?). I have a couple questions: 1) Will I be charged for using my iPhone in WiFi spots? Or is it the same as in the USA, where there's not a charge? 2) I'll be away from WiFi access for the majority of my trip (the last 4 weeks). Is there any way to use my phone during this time? Verizon doesn't seem to serve Turkey...any ideas? Thanks!
